VENTILATED BLOCK.

Specification of Letters Patent. Patented Jan, 1 7

To all whom it may concern Be it known that I, EDWIN L. PAGE, a citizen of the United States, and a resident of Kingsley, in the county of Plymouth and State of Iowa, have invented a certain new and useful Ventilated Block, of which the following is a specification. I 1 The object of my invention is to provide a ventilated building block especially adapted to be used in constructing corn cribs and buildings of that'general type, the block being comparatively cheap and very durable.

More particularly my invention relates to that type of block made with the use of my core for making ventilated blocks, which is made the subject matter of my co-pending application, Serial Number 468,473, filed May 11, 1921. 7

Still another object is to provide a'building block-of greater length than width andadapted to have a pair of openings formed therein, each of the openings being provided with a plurality of blades so positioned that passageways will be had for air, but it will be impossible for rain to pass through said openings. 7

Still another object is to provide the blades with inclined portions, the upper edge of one blade being substantially in the same horizontal plane as the lower edge of the adjacent blade; parts of the blades being embedded in the material from which the block is made for holding the blades in position.

Still another object is to arrange the ends of the blades so that when'they are received in the plastic material from which the block is made they will lie ina plane substantially parallel to the top and bottom of the block.

Still another object is to provide grooves on the sides of the opening and opening into the inner side of the block so that new blades may he slipped into the block if necessary.

With these and other objects in view my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the ob'ects contemplated areattained, as hereina ter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawin s, in which:

igure 1 is a perspective view of one of my ventilated blocks.

Figure 2 is a sectional view taken on the line 22 of Figure 1.

Figure 3 is a side elevation of one of the blades which form the ventilated portion of the block.

and I Figure 5 is a sectional view through one of the blades showing a modified form of anchoring the blades to the block material.

In the accompanying drawings I have used the reference-numeral 10 to indicate generally a block of greater length than width. The block 10 being provided with concave and convex side edges so that when the block is stood on end the abutting edges ofhthe adjacent blocks will co-act with each 0t er.

The block 10 is provided with a pair'of openings 11. The openingsll are provided with a plurality of blades 12. Each of the blades 12 comprise a body portion which is inclined relative to the top and bottom of the block. 1

Each of the blades 12 are provided with ends 13 which are bent relative to the main body portion of the bladeso that it rests in a substantial horizontal plane when in position. r

The ends 13 are of less width than the blade 12. The ends 13 of the blade are permitted to set in the material from which the block is made for thus positioning theblades in the block.

WVhen the blocks are originally made grooves 14 areprovided which are of sub stantially the same length as the ends 13 of the blades, and substantially the same width. The purpose of the grooves 14 will now be mentioned.

It may be stated that some times the blades become broken and it is desirable to replace them. The old blades may be-removed from the blocks and a new blade maiy then he slipped into place.

.t will be understood that the blades are placed in the block when originally made and the ends 13are permitted to set, which ENT QFFICE.

Figure 4 is an end elevation of the blade;-'

will prevent the possibility of the blades 7 of. block will be. ordinarily used, as new blades are only required in exceptlonal 1nstances.

It will be seen that I have provided a very efficient building block which will. prove very eflicient for ventilation, and yet be rain proof.

Some changes may be made in the construction and arrangement of the parts of my block without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims, any modified forms of structure by the use ot'mechanical. equivalents, which may be reasonabl included within their scope.

l claim. as my invention:

1. A ventilated building block having a pair of openings therein arranged, lengthwise of the block, each of said openings being provided with a plurality of inclined blades having their ends embedded in the block for holdingthem in position, the ends of said blades being arranged parallel with the top and bottom'of the block.

j2. A ventilated building block, having a pair of openings therein arranged lengthwise of the block, each of said openings being provided with ir -plurality of inclined blades having their ends embedded in the block for holding them in position, the upper edge of one blade lying in substantially the same horizontal plane as the loweredge of the adjacent blade, the ends 0t said blades being arranged parallel with the top and bottom of the block.

serve as a drain, the upper-edge of one blade being in substantially the same horizontal plane. as the lower edge of the adjacent blade, the ends of the blades being substan tially parallel with the top and bottom of the block, V

4. A ventilated building block having a pair of'openings therein arranged lengtl wise of the block, each, of "said openings being; provided with a plurality of inclined blades having their ends embedded in the block; for holding them in -position,;thc: upper edge ofone blade: lyingin substantially the same horizontal; plane as the lower edge of block.

the adjacent blade, the ends of said blades being arranged parallel with the top and bottom of the block, the sides of said openings being provided with registering grooves so that blades may be slipped into or out of position as desired.

5. A ventilated building block rectangular in outline and of greater length than width. and provided with an opening arranged lengthwise of the block, said opening having a plurality of blades therein, the ends of said blades being of less width than the main body portion of the blades and embedded in the block, the exposed portion of the blades being upwardly inclined from front to rear so as to serve as a drain, the upper edge of one blade being'in substantially the same horizontal plane as the lower edge of the adjacent blade, the'ends of the blades being substantially parallel with the top and bottom of the block.

6'. A ventilated building block of greater length than'width provided with a pair of openings arranged lengthwise of the block, blades received within each of said openings, said blades being of greater length than the width of said openings so that the ends thereof may be embedded in the block, the 7 portion of the blade received! within the opening being substantially wider than the portions received within the block. said first portion of the blades being inclined upwardly. from front to rear so as to serve as a drain, the blades being so positioned that the upper edge of'one blade liesin substantially the same horizontal plane as the lower edge of the adjacent blade, the portions of the blades embedded'inthe block are so arranged that they are, substantially 7 parallel with the top and 'bott'om'of the block. r

7. A ventilated building block having an opening therein arranged lengthwise of the block,.said1opening being provided with a plurality of blades having their ends embedded inthe block for holding them in position, the ends of said blades being arranged parallel with the top and bottom of the 8. A ventilated building block having a pair of openings therein arranged lengthwise of the block, each of said openings being provided with a plurality of blades having their ends embedded in the block for holding them inposition, the ends of said'bladesbeing arranged parallel with the top and: bottom-ofthebloek,
